摘　　要：针对直接节流盘式液阻悬置件,通过材料实验确定了液阻悬置中橡胶材料的本构模型,并建立了液阻悬置的结构模型和液体模型。利用液固耦合有限元分析方法对集总参数模型的相关参数进行识别,在阐明了液阻悬置件减振机理的同时,也获得了液阻悬置件的性能参数。此方法对分析液阻悬置件结构参数与等效参数之间的关系十分有效,为液阻悬置件精准的设计开发与结构优化奠定了基础。Through the study of material testing to determine constitutive model of rubber material included by the hydraulic engine mount,the solid and liquid models on hydraulic engine mount were imported into finite element analysis software to establish a liquid-solid coupling model. It not only clearly explains the relevant mechanisms of reducing vibration,but gets the character of mount. It is effective to study the relationship between structural parameters and equivalent parameters by using this method, which contributes to the precise design development and structural optimizing of hydraulic engine mount.
